Notes

• There were some firmware updates available (see fwupdmgr) when I first received this machine that fixed Linux support for a few things. Everything I've tested so far is now working great.

  • Red LED on back of screen
  • Power button LED
  • Red Charge LED
  • White Charge LED
  • Fn button LED
  • Microphone LED
  • CAPS lock LED
• The one that is NOT working:
  • Mute LED

• Screen backlight control is working via /sys/class/backlight/intel_backlight/brightness (min=0, max=2047)
• Keyboard LED backlight is configurable via /sys/class/leds/tpacpi::kbd_backlight/brightness (0=off, 1=medium, and 2=high)

POST Keyboard Shortcuts

You can access the boot options on your Lenovo ThinkPad X1 Extreme Gen 2 using these keyboard shortcuts:

• Boot Menu: Press F12 or Fn+F12 during bootup when the Lenovo logo appears.
• BIOS Settings: Press F1 or Fn+F1 during bootup when the Lenovo logo appears.
• Startup Interrupt Menu: Press Enter at the Lenovo logo to access a menu from which you can choose to enter BIOS.

In addition:

• Boot from USB: After pressing F12 to access the boot menu, use the arrow keys to select your bootable USB drive and press Enter. You may need to disable Secure Boot in the BIOS settings if you're experiencing issues booting from USB.
• Recovery Mode: If your system has Lenovo OneKey Recovery, you can access it by pressing the Novo button (usually a small button or pinhole with a backwards arrow icon). Then, select "System Recovery" from the Novo Button Menu.

Important Notes:

• Some models may require you to repeatedly tap the chosen key during the boot process.
• If your boot device is disabled in the BIOS, you cannot select it using the boot menu.
• Check your specific model's user guide for detailed instructions and additional options.

Accessing with Broken Screen

Yeah, this happened to me :-(

To access and boot a Lenovo Thinkpad X1 Extreme Gen 2 with a broken screen, you'll need to connect it to an external monitor and use the appropriate function keys to access the BIOS or boot menu to select the desired boot device. Here's a step-by-step guide:

1. Connect to an external monitor: Use an HDMI or DisplayPort cable to connect your Thinkpad X1 Extreme Gen 2 to an external monitor.
2. Force boot to external display: When the computer starts booting, repeatedly press Fn+F7 (or just F7 if your keyboard doesn't have the function lock) to cycle through display options and force the output to the external monitor.
3. Enter BIOS: Press the F1 key (or Fn+F1) repeatedly during startup to enter the BIOS settings. You may need to try a few times as the timing can be tricky.
4. Access Boot Menu: If you need to select a specific boot device, press F12 or (Fn+F12) rapidly and repeatedly at the Lenovo logo during bootup to open the Windows Boot Manager, and choose your desired boot device from the list.
5. Troubleshoot: If the external monitor doesn't show anything, try restarting and holding the power button for 15-20 seconds to clear any residual power, or try resetting the display mode in the BIOS.

Note: If you are unable to see anything on the external monitor, you can try booting into safe mode or using Lenovo diagnostics tools to help isolate the problem.
